Detailed Description

template<Ownership W, MemSpace M>
struct celeritas::StepStateData< W, M >

Gathered data and persistent scratch space for gathering and copying data.

Extra storage scratch and valid_id is needed to efficiently gather and copy the step data on the device but will not be allocated on the host.

Todo:: Refactor the step interface stuff so that we passing params alongside state data to the step interfaces, so that we don't have to keep a copy of the volume instance depth (and for better consistency with the rest of the code).

The documentation for this struct was generated from the following files:
